Thank you for your reply.
But I have a different opinion.
When any directshow application like AMCap or MSN Messenger don't work,
the pc don't need to supply any power to video capture device.
Idle detection for power saving is mandatory for notebook pc.
if UVC wasn't support idle detection,
we must choose preminum logo or power saving ?

Shinji
